Abstract: Some embodiments are directed to a system and a method for estimating gaze from a set of eye measurement points that are indicative of a gaze pattern of a user viewing a scene. Some other embodiments are directed to obtaining sets of eye measurement points from different users viewing the same scene. In another embodiment, the different sets of eye measurement points are mapped to a common coordinate system for reciprocal calibration. In yet another embodiment, a scene transformation for mapping the common coordinate system to a coordinate system associated with the scene can be calculated by matching eye measurement points from the common coordinate system to interest points of the scene. The scene transformation is thereby calculated more accurately than individually calculated scene transformations, thereby providing a more accurate estimate of the gaze points.

Abstract translation: 一些实施例涉及用于从指示观看场景的用户的注视图案的一组眼睛测量点估计注视的系统和方法。 一些其他实施例旨在从观看相同场景的不同用户获得一组眼睛测量点。 在另一个实施例中，将不同组的眼睛测量点映射到用于相互校准的公共坐标系。 在另一个实施例中，可以通过将来自公共坐标系的眼睛测量点与场景的兴趣点相匹配来计算用于将公共坐标系映射到与场景相关联的坐标系的场景变换。 因此，比单独计算的场景变换更精确地计算场景变换，从而提供更精确的凝视点估计。
